Just to let you know I had surgery at Shands with Drs. Antonelli and Neurosurgeon Lewis. The approach was retrosigmoid, tumor was medium size, and this all done in 2005. I have no complaints and was very happy with Dr. Antonelli and his skill as a surgeon who trained under Dr. Rhoton (a pioneer). I am 5 hours from Shands and this makes it difficult to "pop in" for an appointment with Dr. Antonelli.
IMO I definately recommend to all who have treatment "out of town", make sure you or your doctors line up doctors in your home town for any after care that may be needed. I have had one hellofa time with docs in my home town that don't seem to be experienced with AN side effects after treatment and there are patients, me included, that go from one specialist to another searching for answers. I do have issues going on with my good ear, not from anything Dr. Antonelli and his team did as my surgery went well, but as one ENT stated, "I'm complicated due to my x-AN."
I hope this helps with your on-going information collection and am here if needed, you can email me anytime or call to talk.
